Nanoparticles and sunscreen

Nanotechnology has been used in sunscreens for many years. To date, our assessment, drawing on the best available evidence, is that nanoparticulates used in sunscreens do not pose a risk. However, we continue to monitor research and welcome any new research that sheds more light on this topic.

Sunscreen formulas and their components are regulated through the Therapeutic Goods Administration (TGA). In early 2009, the TGA conducted an updated review of the scientific literature in relation to the use of nanoparticulate zinc oxide and titanium dioxide in sunscreens.

The TGA review concluded that:

The potential for titanium dioxide and zinc oxide nanoparticles in sunscreens to cause adverse effects depends primarily upon the ability of the nanoparticles to reach viable skin cells; and

To date, the current weight of evidence suggests that titanium dioxide and zinc oxide nanoparticles do not reach viable skin cells; rather, they remain on the surface of the skin and in the outer layer of the skin that is composed of non-viable cells.

News of this interesting paper in the journal Geophysical Research Letters missing from the ABC."Despite an increase since 1850 AD, the mean SST in the 20th century is still within the range of natural variability during the past 2700 years."

The 20th century warming in SOT is still within variability of late Holocene

A strong coupling of KC, EAM and ENSO exists in late Holocene

MWP has a mean SST lower than RWP and STWP in Okinawa Trough

Most of the temperature reconstructions for the past two millennia are based on proxy data from various sites on land. Here we present a bidecadal resolution record of sea surface temperature (SST) in Southern Okinawa Trough for the past ca. 2700 years by analyzing tetraether lipids of planktonic archaea in the ODP Hole 1202B, a site under the strong influence of Kuroshio Current and East Asian monsoon. The reconstructed SST anomalies generally coincided with previously reported late Holocene climate events, including the Roman Warm Period, Sui-Tang dynasty Warm Period, Medieval Warm Period, Current Warm Period, Dark Age Cold Period and Little Ice Age. However, the Medieval Warm Period usually thought to be a historical analogue for the Current Warm Period has a mean SST of 0.6–0.8°C lower than that of the Roman Warm Period and Sui-Tang dynasty Warm Period. Despite an increase since 1850 AD, the mean SST in the 20th century is still within the range of natural variability during the past 2700 years. A close correlation of SST in Southern Okinawa Trough with air temperature in East China, intensity of East Asian monsoon and the El-Niño Southern Oscillation index has been attributed to the fluctuations in solar output and oceanic-atmospheric circulation.

Climate tsar skirts dysfunctional models to scare us
WILL Steffen continues to promulgate misinformation about the climate ("Clean up energy for the sake of our grandchildren", 23/7). Passing over the rotten entrails of dysfunctional climate models that have not lived up to promise, he has moved on to using extreme weather to scare a populace into extreme action.
So Steffen points to recent weather extremes as portents of a coming doom, claiming it's a future we don't have to have, if only we bow at the Climate Commissioner's altar, shake our tail feathers and pay our dues.
When seen in their historical context, however, the numerous wet and dry periods and extreme weather events that have affected the country are unconnected to carbon dioxide levels. Looking at past weather records it's clearly a future we have already had and one our descendants will continue to experience, regardless of what we do today.
The commission continues to push for inconsequential marginal solutions to our weather and energy problems, ignoring the obvious solutions built around effectively dealing with the extremely routine weather events we know about all too well. If the problem was fixed with levees, dams, and nuclear power what would our witch-doctors do for a living?

The Australian's Cut and paste also adds some cherries missing from Will's basket:Climate researcher Will Steffen in The Australian yesterday:
OVER the past decade, the Swedes have reduced their emissions of carbon dioxide by about 13 per cent, the best performance of any of the world's wealthy countries. Over the same period, the Swedish economy has recorded a higher rate of GDP growth than any of the OECD's "big seven" economies. So much for the myth taking vigorous action on climate change will damage or slow the economy.

Something Steffen forgot to mention? From Energy in Sweden, 2010, Swedish Energy Agency:
IN 2009, nuclear power supplied 37 per cent of the country's electricity, hydro power supplied 49 per cent and wind power almost 2 per cent, with the remaining 12 per cent being made up of fossil-fuelled and biofuel-based production.

Something else Steffen forgot? The Economist, June 6:
ANNUAL growth as high as 6.4 per cent in the first quarter. Unemployment falling fast. The budget in surplus this year. Public debt heading to below 40 per cent of GDP. How did the Swedes do it? . . . the main answer is the prudent pro-market policies of Fredrik Reinfeldt'scentre-right coalition, which came to power in October 2006.

ABC is yet to formally cover news that a paper it widely reported on and promoted was flawed and withdrawn from publication by its authors. The only mention that the paper was withdrawn is in editorial notes posted discretely at the end of articles such as this one: EDITOR'S NOTE: Since this story was originally broadcast, errors have been identified in aspects of the data processing which may affect the results of this study. As a result, publication has been delayed and the research has been withdrawn from online publication. Professor Karoly says the data will be recalculated, peer reviewed and published in due course.

They provide the following response to a query we made regarding missing editorial notes from a number of ABC reports, including one on its ITunes site.

Thank you for your email of 21 June. I apologise for the delay in responding; it took a little longer to sort out iTunes than it should have. The segment on the Radio National website now has a prominent editor’s note and the podcast is no longer available on iTunes.

At this stage, neither Radio nor News propose to do any further broadcasts or stories on the subject. If or when the scientists re-release their research, the story will be reassessed in the normal way taking account of editorial priorities at the time.

ABC's alarmist reporter Mark Willacy gets sucked in by a study that claims "the Fukushima nuclear disaster in Japan may eventually cause up to 1,300 deaths." There is not a skerrick of journalistic scepticism in ABC's report. Andrew Bolt provides some missing background in his criticism of a similar piece published by the Fairfax Press.

Here's the gist of it:

Here’s a few facts omitted from the article - facts which suggest the findings are alarmist trash.

- Jacobson (co-author of the study) is a long-time anti-nuclear activist and global warming campaigner.

Demetris Koutsoyiannis continues to be a missing voice on the ABC (Search results from the entire ABC site...No matching documents found). He is professor in Hydrology and Analysis of Hydrosystems, and Head of the Department of Water Resources and Environmental Engineering of the National Technical University of Athens. He is also Co-Editor of Hydrological Sciences Journal and member of the editorial board of Hydrology and Earth System Sciences (and formerly of Journal of Hydrology and Water Resources Research). He has been awarded the Henry Darcy Medal 2009 by the European Geosciences Union for his outstanding contributions to the study of hydrometeorological variability and to water resources management. Seems like someone Robyn Williams should be talking to.

Despite his outstanding record, ABC have not chosen to speak with Prof. Koutsoyiannis, and they have ignored his latest work that highlights issues with statistical methods used to iron out problems with temperature data. Here's the title and abstract:

We investigate the methods used for the adjustment of inhomogeneities of temperature time series covering the last 100 years. Based on a systematic study of scientific literature, we classify and evaluate the observed inhomogeneities in historical and modern time series, as well as their adjustment methods. It turns out that these methods are mainly statistical, not well justified by experiments and are rarely supported by metadata. In many of the cases studied the proposed corrections are not even statistically significant.

From the global database GHCN-Monthly Version 2, we examine all stations containing both raw and adjusted data that satisfy certain criteria of continuity and distribution over the globe. In the United States of America, because of the large number of available stations, stations were chosen after a suitable sampling. In total we analyzed 181 stations globally. For these stations we calculated the differences between the adjusted and non-adjusted linear 100-year trends. It was found that in the two thirds of the cases, the homogenization procedure increased the positive or decreased the negative temperature trends.

One of the most common homogenization methods, ‘SNHT for single shifts’, was applied to synthetic time series with selected statistical characteristics, occasionally with offsets. The method was satisfactory when applied to independent data normally distributed, but not in data with long-term persistence.

The above results cast some doubts in the use of homogenization procedures and tend to indicate that the global temperature increase during the last century is between 0.4 C and 0.7 C, where these two values are the estimates derived from raw and adjusted data, respectively.

The past history of the AMO is preserved in ice core data
The dominant quasi-periodicities are those of 20 years and 45-65 years
The origin of 20-year periodicity is Atlantic and of 45-65 year the Arctic

Medieval Warm Period (950 - 1250) and Little Ice Age (1450 - 1850) are the most recent periods that reflect the magnitude of natural climate variability. As their names suggest, the first one was characterized by higher temperatures and a generally moister climate, while the opposite happened during the second period. Although their existence is well documented for Northern Europe and North America, recent findings suggest strong evidence in lower latitudes as well. Here we analyze qualitatively the influence of these climatic fluctuations on the hydrological cycle all over the Mediterranean basin, highlighting the spatial characteristics of precipitation and runoff. We use both qualitative estimates from literature review in the field of paleoclimatology and statistical analysis of proxy data series. We investigate possible regional patterns and possible tele-connections with large scale atmospheric circulation phenomena such as North Atlantic Oscillation, Siberian High, African Sahel Rainfall and Indian Monsoon.

A multiproxy palaeolimnological study of climate and nutrient impacts on Esthwaite Water, England over the past 1200 years
The Holocene January 2012 vol. 22no. 1 107-118 Xuhui Dong, Helen Bennion, Richard W. Battarbee, Carl D. SayerAbstract
The response of diatom assemblages to changes in climate and nutrients over a 1200 year timescale was investigated by means of a multiproxy sediment core study involving radiometric dating, diatoms, grain size, loss on ignition and geochemical analysis. Four stages of environmental change were defined, each being consistent with changes in documented human activity and known climate patterns. From AD 750 to 880 relatively high nutrient status and a cold, unstable climate was inferred based on the high abundance of Aulacoseira subarctica and high Na/K and Na/Al values. In the following 1000 years (AD 880–1880) diatom assemblages were dominated byCyclotella comensis, Cyclotella radiosa and Achnanthidium minutissimum, suggesting a long period of relatively low productivity and, by implication, that climate was the main control on the community during this period. Two climatic phases, namely the ‘Medieval Warm Period’ (MWP) and the ‘Little Ice Age’ (LIA), were apparent. According to shifts in the diatom assemblages and other proxies, it was proposed that the MWP was initiated from ~AD 880 and was terminated by the LIA at ~AD 1350. After AD 1880 the palaeoecological data revealed a period of strong human impact in the catchment and hence higher productivity. This work illustrates the complexity of climate–nutrient interactions and the roles of the two drivers on different timescales and at various stages of the lake’s history: climate impacts were more pronounced when nutrient concentrations were relatively stable prior to ~AD 1880; while nutrients appeared to play a more important role in regulating diatom communities from the mid-eighteenth century.

The reconstruction provides a high-resolution representation of temperature patterns in the Roman and Medieval warm periods, but also shows the cold phases that occurred during the Migration Period and the later Little Ice Age.

According to the press release the paper, published in Nature Climate Change titled Orbital forcing of tree-ring data: An international team including scientists from Johannes Gutenberg University Mainz (JGU) has published a reconstruction of the climate in northern Europe over the last 2,000 years based on the information provided by tree-rings. Professor Dr. Jan Esper's group at the Institute of Geography at JGU used tree-ring density measurements from sub-fossil pine trees originating from Finnish Lapland to produce a reconstruction reaching back to 138 BC. In so doing, the researchers have been able for the first time to precisely demonstrate that the long-term trend over the past two millennia has been towards climatic cooling. "We found that previous estimates of historical temperatures during the Roman era and the Middle Ages were too low," says Esper. "Such findings are also significant with regard to climate policy, as they will influence the way today's climate changes are seen in context of historical warm periods."

The PR ConcludesIn addition to the cold and warm phases, the new climate curve also exhibits a phenomenon that was not expected in this form. For the first time, researchers have now been able to use the data derived from tree-rings to precisely calculate a much longer-term cooling trend that has been playing out over the past 2,000 years. Their findings demonstrate that this trend involves a cooling of -0.3°C per millennium due to gradual changes to the position of the sun and an increase in the distance between the Earth and the sun.

"This figure we calculated may not seem particularly significant," says Esper. "However, it is also not negligible when compared to global warming, which up to now has been less than 1°C. Our results suggest that the large-scale climate reconstruction shown by the Intergovernmental Panel on Climate Change (IPCC) likely underestimate this long-term cooling trend over the past few millennia."

I made an enquiry regarding the manner in which ABC manages its online news archive a little while ago to your senior staff including Alan Sunderland, Bruce Belsham and Angela Clark (see HERE). None of these staff members has been at all helpful in providing any information about the manner in which stories are posted to the archive, or about recent changes that have resulted in the apparent removal of 10,000s reports from the archive since 2003.

I have been using the Online News Archive as a measure of ABC news productivity. Since 2007 there has been a marked decline in the number of stories posted the archive (see HERE and HERE).

I am trying to establish if this is a result of a policy decision related to managing the archive, or a true reflection of declining news coverage. Perhaps reflecting a fall in the number of regional stories being covered by the ABC at the expense of opinon pieces?

As I mentioned to your staff above, ABC's NEWS archive represents an important, growing source of historical news information, and as such some explanation as to why the number of posts to it have been falling is deserving of some explanation. If this is a matter of policy, then perhaps it can be corrected so that all the news makes it into the archive, and not a "cherry picked" sub-sample. ABC's growing archive will no doubt be important in helping future historians unpick past events, the more complete it is the better it will be.

I note that this year ABC is consistently posting 250 stories for Tuesday-Friday (ed actually its the whole week M-F), including numerous opinion pieces not previously included. Is the inclusion of opinion an attempt to cover for falling coverage of news stories?

Of greater concern I also note that the remainder of the archive, since 2003, appears to have been retrospectively culled of reports such that the total number of stories posted each week day has also been reduced to 250. This has involved removal of 10000s of reports and seems to represent a deliberate destruction of the value of the archive for historical research purposes.

I have collected records of the number of stories posted to the archive for each day in the month of June from 2003 to present as part of the productivity report. The numbers can be confirmed through the online internet archive (see HERE). I have not had the opportunity to go back through each year. For June 2003 the effect is dramatic with over 590 stories removed. For June 2004 it seems there are 171 less now compared to 2010 when we first used the archive to report on ABC's productivity. For the year of 2008 when we originally counted a record 8894 stories for June, ABC's archive now contains 6618 stories. It seems that for just one month ABC have culled 2276 reports from history! And this just for the month of June, extended over the whole archive it means 10,000s of stories have been evaporated, akin to literally cutting the stories from the pages of an archived newspaper

Specific questions:
1. What is ABC's policy, if any, regarding its Online News Archive?
2. Do the falling number of items since 2007 reflect a fall in news productivity, or are they the consequence of a change in records policy?
3. On what grounds does ABC decide to include news items in its archive?

4. Why did ABC cull its news archive to remove easy accessibility to 10000s of stories? Which stories? Why? How-what criteria were used for the cull?

5. Can we expect to see the full archive restored? When?

The lack of a satisfactory timely response and deliberate refusal to cooperate with seemingly legitimate requests on this matter is of some concern hence I have cc'd this email to Senator Conroy, Malcolm Turnbull, Senator Fierravanti-Wells, along with a representative from the mainstream press to draw attention to the issue.

Some screen shots below showing the effect of the cull of reports from ABC's News Archive: The Wayback Machine, the Internet archive, has preserved some glimpses of ABC's Archive for posterity. We looked at June 16, 2008 when ABC News posted a record 392 reports. The Wayback machine archive captured on 2 February 2011 confirms our earlier count, showing 15 pages with 25 reports each, with the 16th page containing 17 reports. As of this morning the ABC's achive shows just 10 pages, each with 25 reports for a total of 250 reports, meaning access to 142 reports through the archive have been removed, effectively culled (see comparison of screen shots below-click to enlarge). It seems that reports prior to about midday, in this case, have been sent down the memory hole.

Why the ABC have placed a limit on the number of stories in its archive remains a mystery. It seems at this point that attempts to thwart our productivity survey at least one possible reason, incompetence always another.

Perhaps using George Orwell's 1984 as an instruction manual ABC have apparently, sometime in the last 12 months, removed large numbers (10,000's) of stories from its online news archive. Is this a means to hide the dramatic decline in its news productivity? Which stories were removed and why? What a radical re-writing of history! Or is it just a technical glitch?

ABC NEWS WATCH has been looking at the productivity of ABC news since 2010. As a measure of ABC's news productivity we have been using the number of stories posted to ABC's online news archive in June and its staff numbers from annual reports to help gauge its output. ABC senior staff have been reluctant to assist us with information about how the archive is managed (see correspondence in part 1). The figures show a dramatic decline in productivity since 2007.

Looking over the number of stories posted for this year it became apparent that ABC have set a limit of stories that are posted to its archive in June this year. The limit appears to be set at 250 stories per day Monday to Friday. Weekend figures do not appear to have been adjusted.
To our surprise it appears this limit has been retrospectively applied to ABC's entire online archive since 2003. If true, this means that literally 1000s of stories have been culled (UPDATE make that 10,000s).
I have records of the number of stories posted for each day in the month of June from 2003 to present. I have not had the opportunity to go back through each year. For June 2003 the effect is dramatic with over 590 stories removed. For June 2004 it seems there are 171 less now compared to 2010 when we first reported on ABC's productivity. For the year of 2008 when we originally counted a record 8894 stories for June, ABC's archive now contains 6618 stories. It seems ABC have culled 2276 reports from history! And this just for the month of June, extended over the whole year it means 10,000s of stories have been evaporated.

Which stories? Why? How-what criteria were used for the cull? Or is this just a fat finger moment?More on this as we find out what has happened.

We have archived some of the revised archive pages at webcite for posterity (eg HERE).

UPDATE: See Part 2 for news of an emerging scandal involving potential manipulation of ABC's online News Archive.

Update 10 July 2012. Still no word from ABC on the reasons for the cull. Bruce Belsham has now moved on to current affairs. I passed the email below on the new Director of Innovation: Angela Clark and did not receive any assistance. See comments for the content.

Here are the results of this years productivity survey. First the facts (2012 in orange, note the flat peaks Monday to Friday-click to zoom):

Productivity: Based on the Raw numbers it comes at no surprise that ABC news productivity is once again at arecord lowwith just 6.1 stories per staff member for the month. Year Stories per staff per month2003 9.42004 9.42005 9.12006 9.12007 9.52008 10.32009 7.82010 7.12011 6.12012 6.1

ABC Hiding the decline
ABC News management seems to have taken some unusual steps in hiding the decline in its productivity by this year introducing a "cap" on the number of stories contained in its online news archive this year (note the flat peaks in the number of stories Monday to Friday in the graph above). It seems stories Monday-Friday have been artificially capped at 250, no more. This has been achieved by including an arbitrary selection of video and audio news files (eg the news weather report) to raise the online reports each day to 250 stories. We have not taken the time to go through the number of video and audio stories added to bolster the stories to 250 each day.

UPDATE. IT APPEARS ABC HAVE APPLIED THIS LIMIT RETROSPECTIVELY TO THEIR ENTIRE NEWS ARCHIVE. THIS MEANS A LARGE NUMBER OF STORIES HAVE BEEN REMOVED FROM THE ARCHIVE. WHICH STORIES WERE REMOVED? AND WHY? SEE PART 2. (OR PERHAPS IT'S A TECHNICAL GLITCH?)

After a less than satisfactory response from ABC's head of News Policy, Alan Sunderland (see lengthy exchange below) we asked ABC's Online Editor Bruce Belsham for an explanation, so far he has not responded to our enquiries. Here's the email we sent Bruce:UPDATE 8/7/2012 8pm: It seems Bruce has moved on we have forwarded the email below to Angela Clark, head of ABC Innovation.

query regarding ABC news Archive

Dear Bruce,

In previous correspondence with Alan Sunderland regarding ABC's online news archive the following issues were raised. Alan was unable/unwilling to provide any answers perhaps you can assist.

I have been looking at using the Online News Archive as a measure of ABC news productivity. Since 2007 there has been a marked decline in the number of stories posted the archive (see Here) I am trying to establish if this is a result of a policy decision or a true reflection of declining news coverage. Perrhaps reflecting a fall in the number of regional stories at the expense of opinon pieces?

As I mentioned to Alan ABC's NEWS archive represents an important, growing source of historical news information, and as such some explanation as to why the number of posts to it have been falling is deserving of some explanation. If this is a matter of policy then perhaps it can be corrected so that all the news makes it into the archive and not a "cherry picked" sub-sample.

ABC's growing archive will no doubt be important in helping future historians unpick past events, the more complete it is the better it will be.

I note that this year ABC is consistently posting 250 stories for Tuesday-Friday, including numerous video and opinion pieces not previously included. Is the inclusion of opinion and video an attempt to cover for falling coverage of news stories?

Specific questions:

1. What is ABC's policy, if any, regarding its News Archive?

2. Do the falling number of items since 2007 reflect a fall in productivity or are they the consequence of a change in policy?

3. On what grounds does ABC decide to include news items in its archive?

Marc,On another matter, I note that you did get a response to the ABC about your request for productivity information, but it was not a particularly useful one as you sent it to A&CA instead of to us. I think that was pointed out to you at the time, but I have no record that you followed it up with News.Based on your brief description to me of the methodology you rely upon to measure productivity (count up all staff employed by news in all areas and then count up the number of news stories appearing on the News website), I can see all sorts of basic problems with it.However, I confess I am reluctant to spend too much time on this if you are not genuinely interested in the issue beyond making a point on your website.I could provide you with substantial material on our divisional output, and the extent to which it has grown in recent years, and I could also seek some more detailed information from News Online on their strategies for what they post and why they post it, but I am concerned that this is not information you really want to hear, and I may be wasting my time.Are you only interested in what I see as a crude and misleading correlation between the stories posted on one of our divisional websites when cross-referenced with the entire divisional staff employed in News, News 24, 7.30, Behind the News, Radio Australia, etc...etc...etc..., or are you interested in the bigger and more accurate picture?

subject: Re: updates to last year's death threat story-more corrections required

Dear Alan,
To make it clear; I would be very grateful if you could seek more detailed information from News Online on their strategies for what they post and why they post it. I would be more than happy to post such an explanation on my website along with this year's productivity survey results.
Unlike ABC I am interested in getting accurate information and hence my request to the ABC for an explanation for the apparent fall in NEWs' productivity. That is has taken this long to get a response, a sign perhaps that ABC believes it is above the requests of mere mortals.
As I mentioned ABC's NEWS archive represents an important, growing source of historical news information, and as such some explanation as to why the number of posts to it have been falling is deserving of some explanation. If this is a matter of policy then perhaps it can be corrected so that all the news makes it into the archive and not a "cherry picked" sub-sample.
ABC's growing archive will no doubt be important in helping future historians unpick past events. For instance it will provide a valuable resource for future historians in helping assess the extent and detrimental impact that ABC's Groupthink reporting had on public policy in the early 2000s.

Marc,I am sorry you have chosen to handle my genuine offer to engage in this manner.I don't see that there is anything further I can usefully provide by way of information, since you have already formed and expressed your conclusions.

Alan,
Which part of my response did you not understand

Dear Alan, to make it clear; I would be very grateful if you could

By the way looking forward to ABC's update to its numerous stories regarding the paper documenting Southern Hemisphere temperature reconstruction (for instance: 1000 years of climate data points to a warming Australia). Seems the paper has been withdrawn from publication following the discovery of errors in the methodology.

see David Karoly's letter to Steve McIntyre: Print publication of scientific study put on holdAn issue has been identified in the processing of the data used in the study, “Evidence of unusual late 20th century warming from an Australasian temperature reconstruction spanning the last millennium” by Joelle Gergis, Raphael Neukom, Stephen Phipps, Ailie Gallant and David Karoly, accepted for publication in the Journal of Climate.We are currently reviewing the data and results.

Marc…
Thanks for bringing this to my attention.
Clearly, given that we have reported on the study, we would want to be across any material changes to it. I have brought this to the attention of the reporters who filed the original pieces, so that we can track the process and take account of any updated or changed information.

A week off including a day in the snow at Selwyn. Here's some commentary from John Roskam that rings true...

Aunty looms too large"The ABC is cutting up and eating Fairfax and News’s lunch. It’s not Gina Rinehart and Rupert Murdoch that journalists should be worried about. It’s Mark Scott, the boss of the ABC, they should fear."

"Media concentration in Australia is all going one way – and it’s in the direction of the ABC."

Aim of ABC NEWS WATCH

In a diversifying media landscape news editors face an increasingly difficult challenge reviewing the work of reporters under their supervision. Inevitably some mistakes, errors and substandard articles slip past their critical eyes.

The simple aim of ABC NEWS WATCH is to publicise the errors, omissions, and substandard reports produced by the News service and related entities of the Australian Broadcasting Corporation (ABC). In doing so we hope to provide an independent check or audit on ABC news articles and in doing so improve the standard of ABC news reporting. After all it's our ABC.

We acknowledge and pay respect to the actions, sacrifice, wisdom, traditions, mistakes and curiosity of our ancestors. Their collective efforts over centuries helped evolve our western civilisation, giving birth to the liberal society that makes this website possible.
